This product is a replacement LED light unit for the Current USA Orbit R24 system, specifically designed for reef aquariums. It provides compact yet powerful illumination engineered for robust SPS coral growth and enhanced coloration. This light unit serves as a direct replacement or an upgrade component, integrating seamlessly with existing Orbit R24 setups. Boasting a compact 5x5 inch footprint, this 52-watt LED light delivers a peak PAR of 100 umol at a 24-inch depth, with a recommended SPS spread of 20x20 inches and a maximum spread of 24x24 inches. It features a precise array of powerful dual-core LED chips that emit an optimized reef-specific color spectrum, including a higher ratio of blue LEDs balanced with full spectrum light. Proprietary optical lenses ensure superior color blending, broad spread, desirable shimmer, and excellent penetration. The marine-grade aluminum body incorporates a thermally efficient wide channel heatsink for quiet, passive cooling. This replacement Orbit R24 Reef LED is ideal for serious reef aquarium hobbyists seeking to maximize SPS coral growth, health, and vibrant coloration in their tanks. It is perfect for those who already own the Current USA Orbit R24 system and require a replacement light unit or wish to expand their lighting capabilities. Users should note that the power supply, tank or stand mount, and mini Bluetooth controller are sold separately, making this best suited for individuals who have these components or plan to acquire them independently to complete their lighting setup.
